veniently arrangedin a 'carpenters tool chestv and, thereby carried from place to place. i Y" More specifically stated, the invention contemplates a trestle wherein the supporting beam includes hingedly connected sections capable of being folded side by side, and spaced pairs of divergently disposed legs A which are also capable of being swung to a,

folded position in parallelism with the respective halves of the suporting beam.

Another object of the invention resides in providing a trestle wherein the supporting beam is designed to provide the necessary strength and rigidity at the meeting ends of the respective halves of said beam, and which beam also embodies relatively adjustable sections which can be extended to in-' crease the length of the beam if found necessary to do so.

Other objects and advantages of the invention will be better understood whenthe following detailed description is read in connection with the accompanying drawings,

the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indi cate similar parts in the several views, and wherein:

Figure 1 is a view showing the invention I in side elevation.

Figure 2 is an end elevation.

Figure 3 is a perspective view showing the trestle folded.

Figure 4 is a transverse sectional View showing how the supporting legs are connected with the body of the trestle.

Figure 5 is a sectional View showing the connection between the respective sections of each supporting leg.

Figure 6 is a transverse sectional view showing how the parallel members includ- Figure ing' the adjustable section are connected together.

view of the adjustable member. Referring to the drawings in detail,,A Indicates the-cross beam of thetrestle which is made up of halves indicated at 11-0 and 11 respectively, and which halves are'hingedly connected together as at12, so that'the beam can be folded in a manner to be hereinafter described. Arranged upon and forming part of each-half is a pair of spaced parallel members of relatively different lengths, the member 12I being comparatively short, while the. member 131is of a length to extend beyond the hinged joint'between the respective halves of the supportingbeam. It will be further notedthat the long sections 13 carried by these respective halves are arranged adjacent the opposite longitudinal edgesof the beam and overlap thehinged joint for the purpose of affording the beamthe proper strength and rigidity when the trestle is set up for use. Arranged to slide between the parallel members 12 and 13 carried by each half ofthe beam is an adiustable section l l which can be extended to increase the length of the beam as the occasion mayrequire. these sections are equal to the length of the supporting beam. so that when not in use, they are arranged end to end, and'also add to the strength and rigidity of the beam proper. Each section 14 is longitudinally slotted as at 15 to receive a cross bolt 16 equipped with a winged nut 17 These slots allow the sections to be adjusted in the manner above described, while thebolts 16 limit the sliding movementsof the sections, and also prevent the sections from being accidentally separated from the supporting beam, when the winged nut is tightened the sections are held fixed relatively to the beam as will be readily understood.

The beam is supported by spaced pairs of divergently disposed legs. and the legs of each pair are made up of adjustable sections 18 and 19, the latter being pivoted upon the section 18 by means of a bolt 20 which is passed through the sections and has associated therewith a winged nut 21, the section 19 can be swung to lie upon the section 18,

- sockets 24 carried by the supporting beani or to be swung to lie at opposite sides and in fiaralllism Withthe respective halves of said beam. w

By' reasoi iof the constri-ietioir illustrated ass described it isnianifest that the trestle Ca n be quickly and conveniently set for use, and just as easily knocked do W11 and folded to previde a comparatively sm al l article;

which Canbearranged in 'a' tool chest or the like. In order to" fold the trestle it is only necessary to arrange the sections 19 of the various legs upon the sections 18, after which the legs pulled out of their re-' speetive sockets, then Swen-g 3:0 lie at oppe'site sides of the beam parallel there with; The beam is then broken ifithe' cen ter so that the halves 10 and 11 are arranged sidebyside as shown.

Vliil' it is believed that from the foregoing description,- the nature and advantages of the invention Will be readily apparent, I desire to have it understood that I do not limit myself to What is herein shown and described, and that such changes may be resorted to Whendesired as fall Within the scope of What is claimed.

Havi-irg thus described the invention, I claim:

i Ina trestle, su pporting beam including hingedly connected sections adapted to be arranged in end to end relation for use,- and folded in parallelism when not in use,

spaced parallel strips arranged upon each through the slot of the auxiliary section,

and nut associated with said bolt, whereby'said auxiliary section may be held fixed any given position, and legs for said trestle. V v

In testimony whereof I afiiX my signature.
